adjective Referring to enlarged cells or red blood cells.

anemia

Hematology A condition characterized by ↓ RBCs or Hb in the blood, resulting in ↓ O₂ in peripheral tissues Clinical Fatigability, pallor, palpitations, SOB; anemias are divided into various groups based on cause–eg, iron deficiency anemia, megaloblastic anemia–due to ↓ vitamin B₁₂ or folic acid, or aplastic anemia–where RBC precursors in BM are 'wiped out'. See Anemia of chronic disease, Anemia of investigation, Anemia of prematurity, Aplastic anemia, Arctic anemia, Autoimmune hemolytic anemia, Cloverleaf anemia, Congenital dyserythropoietic anemia, Dilutional anemia, Dimorphic anemia, Drug-induced immune hemolytic anemia, Fanconi anemia, Hemolytic anemia, Idiopathic sideroblastic anemia, Immune anemia, Iron-deficiency anemia, Juvenile pernicious anemia, Macrocytic anemia, Megaloblastic anemia, Microcytic anemia, Myelophthisic anemia, Neutropenic colitis with aplastic anemia, Nonimmune hemolytic anemia, Pseudoanemia, Refractory anemia with excess blasts, Sickle cell anemia, Sideroblastic anemia, Sports anemia.
